Expert Review by Jed
The Twin size Sealy Posturepedic Response Premium Warrenville IV Cushion Firm Pillow Top Mattress is one of the most comfortable mattresses in the line for single sleepers who like the initial softness of a pillow top with firm underlying support. In addition to great comfort, this mattress also features a wide variety of improvements from the previous generation III Warrenville model, including the quilt, coil system, edge support, and foam quality.

Starting at the top, the first improvement comes from the SupremeLoft Cover with MoistureProtect and AllergenProtect Technology found in the quilt. This top-tier fabric is designed to draw moisture away from your body to protect against dust mites and dander for a clean and fresh sleep environment. Next, all of the comfort components used in the Warrenville IV are now CertiPUR-US certified to meet or exceed the highest quality standards in bedding. Comfort layers include Sealy Cushion Air Ultra Soft Foam, which supplies the initial contouring and softness of a pillow top while promoting good airflow. Next, the layer of Sealy Cushion Extra Soft Foam delivers deep pressure relief to help reduce tossing and turning and promote good blood circulation. A layer of Sealy Support Foam prevents the mattress from becoming overly soft, and it helps contribute to the firm underlying feel I previously mentioned. Lastly, another layer of Sealy Support Foam builds upon the already firm underlying feel. This mattress utilizes Posturepedic Technology in the center third to enhance support. This is done through the SealyCool Gel Memory Foam located in the center third as well as the zoned design found in the coil system. Speaking of the coil system, the Sealy Response Pro HD Encased Coil System boasts a higher coil count than the generation III model, and it also provides zoned support to the lower back. The individually wrapped design contours well to the body while guaranteeing solid support. It's adjustable base compatible, and it provides good motion isolation. This means that when movement takes place on one side you feel less on the other. Last but not least, the DuraFlex Edge provides a fantastic edge support and consistent comfort, even when sleeping to the edge. This is a significant improvement over the already good foam encasement used in the previous generation III model.

All in all, if you enjoy a firm underlying feel but want enough padding to sink in a bit at night, the Twin size Sealy Posturepedic Response Premium Warrenville IV Cushion Firm Pillow Top Mattress is one of the best choices on our site. The improvements from the last generation make this model an even better value than before, and it's made to last the next 10 or more years.
